  • Patent number: 8932137
    Abstract: The invention provides for an automated data collection having an endpoint coupled to at least one gaming machine to collect data from the at least one gaming machine, at least one concentrator in communication with the endpoint via a personal area network to obtain the data from the endpoint, and at least one remote collection server in communication with the at least one concentrator to receive the data from the at least one concentrator, wherein the data is pushed from the endpoint to the at least one remote collection server at predefined time intervals without interrupting game play on the at least one gaming machine.

  • Publication number: 20100103092
    Abstract: A video-based character input apparatus includes an image capturing unit, an image processing unit, a one-dimensional feature coding unit, a character database, a character recognizing unit, a display unit, and a stroke feature database. The image capturing unit captures an image. The image processing unit filters a moving track of a fingertip in the picture by detecting a graphic difference, then detecting a skin color and picking out a moving track most corresponding to a point of the object. The one-dimensional feature coding unit takes a stroke with respect to the moving track and converts the stroke into a coding sequence in a one-dimensional string according to a time sequence. The character recognizing unit proceeds with character comparison between the coding sequence in a one-dimensional string and the character database to find out a character having the most similarity for display one the display unit.

  • Patent number: 7680973
    Abstract: The invention provides for a sideband signal for the USB that has real-time interrupt capabilities. A system and method for hardware detection of an interrupt signal provides for the ability to superimpose a high frequency interrupt signal on a USB power line for transmission to a controller. Alternatively, an overcurrent flow may be generated from a peripheral device and detected by an overflow current detector on the USB. In response, the overflow current detector may output an interrupt/overflow current detection signal to the controller.

  • Publication number: 20050282603
    Abstract: A gaming machine having a non-contact user interface and methods for receiving input to the gaming machine using the non-contact user interface are described. The gaming machine described can receive player tracking information associated with a player, where the player tracking information can include personalization information associated with the player. The gaming machine can receive a signal provided by the player at a non-contact interface device. Next, the gaming machine can decode the signal.
